Well, your first problem is that the draw.ss teachpack uses graphical 
primitives to draw to the screen. MzScheme as you're running it 
explicitly excludes all graphical primitives.  For this, you'll need at 
a minimum to be running MrEd.  Then, you'll start running into other 
problems.  Really, it appears to me that the simplest solution is just 
to use DrScheme.
